What is the value of xx) = 9^x when x= -2?<br><br>A. 1/81<br><br>B. 81<br><br>C. 1/81<br><br>D. 18

Paraphin [41]

Answer:

C. $9^{-2} = \frac{1}{81}$

Step-by-step explanation:

Given

$9^{x}$

Required

Find the expression where x - 2

$9^{x}$

Substitute 2 for x

$9^{-2}$

From law of indices which states

$a^{-b} = \frac{1}{a^b}$

So, the expression becomes

$9^{-2} = \frac{1}{9^2}$

Expand the denominator

$9^{-2} = \frac{1}{9 * 9}$

$9^{-2} = \frac{1}{81}$

Hence, $9^{x}$ is $\frac{1}{81}$ when x = 2

How to convert 8.5% to a fraction

Oliga [24]

Well, to start off you divide 8.5 by 100, this gives you 0.085.

This, when multiplied by 1000 to make it a whole number equals $\frac{85}{1000}$

When simplified this will equal $\frac{17}{200}$

Trigonometry<br> Trigonometric Functions<br> Given: Sin θ = (5/6), Find: Cot θ

nikklg [1K]

Answer:

cotθ = $\sqrt{11}$ $/ 5$

Step-by-step explanation:

sine = opposite / hypotenuse

cotangent = adjacent / opposite

So first we have to solve for the adjacent side b, using pythagorean theorem

$a^{2} +b^{2} =c^{2}$

$5^{2} +b^{2} =6^{2}$

$25 + b^{2} = 36$

$b^{2} = 11$

$b = \sqrt{11}$

cotangent = adjacent / opposite

cotθ = $\sqrt{11}$ $/ 5$
